Spectrophotometric determination of ferrate (Fe(VI)) in water by ABTS

A new method for the determination of low concentrations (0.03−35 μM) of the aqueous ferrate (Fe(VI)) was developed. The method is based on the reaction of Fe(VI) with 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) which forms a green radical cation (ABTS +) that can be measured spectroph...
